用琼脂培养的烟草髓组织(威斯康星州38号)，在黑暗或光照下培养36天。在含有1μ吲哚-3-乙酸的条件下，光照条件下发生了包括器官发生在内的大量分化，而黑暗条件下分化不明显。当2.4-二氯苯氧基乙酸(2，4-D)或萘乙酸(NAA)取代IAA时，分化的光增强作用没有发生。持续时间超过12天的蓝光是光增强效应的原因。
Agar-grown cultures of tobacco pith tissue (Wisconsin 38) were incubated in the dark or in the light for 36 days. With 1 μM indole-3-acetic acid (IAA) in the medium, considerable differentiation, including organogenesis occurred in the light, but not in the dark. Such photoenhancement of differentiation did not occur when 2.4-dichlorophenoxy acetic acid (2,4-D) or naphthalene acetic acid (NAA) was substituted for IAA. Blue light of greater than 12 days duration was responsible for the photoenhancement effect.
